Discover scientifically-validated personality assessments that help you build stronger teams, reduce turnover, and make confident hiring decisions.
Explore Our Hiring SolutionsAs hiring professionals who've spent over a decade helping companies refine their recruitment processes, we've witnessed firsthand the evolution of talent assessment tools. Among all the innovations we've seen, few have been as transformative—or as misunderstood—as the pre-employment personality test.
If you're a hiring manager, HR professional, or business owner grappling with how to identify the right cultural fit while avoiding bias, you're not alone. The challenge of predicting job performance and team dynamics from interviews alone has led many organizations to embrace personality assessments as part of their screening process.
But here's what we've learned: not all personality tests are created equal, and knowing how to use them effectively can make the difference between building a thriving team and making costly hiring mistakes.
What Is a Pre-Employment Personality Test?
A pre-employment personality test is a standardized assessment tool designed to evaluate a candidate's behavioral tendencies, work style preferences, and personality traits that may impact job performance. Unlike skills assessments that measure what someone can do, personality tests explore how they're likely to do it.
These assessments typically examine dimensions such as:
- Communication style and interpersonal approach
- Decision-making patterns under pressure
- Motivation drivers and what energizes performance
- Stress tolerance and resilience factors
- Leadership potential and team collaboration preferences
- Cultural fit indicators for your specific work environment
The key distinction here is that reputable personality tests don't label candidates as "good" or "bad." Instead, they provide insights into whether someone's natural working style aligns with the role requirements and team dynamics.
The Most Effective Personality Assessment Models for Hiring
Through our extensive experience implementing personality testing across diverse organizations, we've identified four assessment frameworks that consistently deliver the most actionable hiring insights.
DISC Assessments: Understanding Communication and Work Styles
DISC has emerged as one of the most practical personality testing frameworks for hiring decisions. Based on decades of research, DISC measures four primary behavioral tendencies that directly impact workplace performance.
Reveals how candidates approach challenges and make decisions. High-D individuals typically excel in leadership roles, competitive environments, and situations requiring quick decision-making. They're direct communicators who focus on results and aren't afraid of conflict. However, they may struggle in roles requiring extensive collaboration or detailed analysis.
Measures social interaction preferences and communication style. High-I candidates often thrive in sales, marketing, customer-facing roles, and team environments. They're enthusiastic communicators who build relationships easily and motivate others effectively. The downside can be difficulty with detail-oriented tasks or working independently for extended periods.
Indicates preference for stability, routine, and supportive relationships. High-S individuals excel in roles requiring patience, consistency, and team support. They're reliable, loyal, and create harmonious work environments. However, they may struggle with rapid change, high-pressure situations, or roles requiring aggressive sales approaches.
Reflects attention to detail, analytical thinking, and quality focus. High-C candidates perform exceptionally in roles requiring precision, compliance, research, or technical expertise. They provide thorough analysis and maintain high standards. The challenge comes with roles requiring quick decisions, extensive social interaction, or frequent change.
What makes DISC particularly valuable for hiring is its immediate applicability. Managers can quickly understand how to communicate with, motivate, and manage different DISC styles, leading to better onboarding and performance management.
The Strengths Test: Comprehensive Talent Identification
The Strengths Test represents the most comprehensive approach to identifying natural talents, measuring 38 distinct strengths across five core domains. With over 4 million professionals having taken this scientifically-validated assessment, it provides unparalleled insights into how candidates naturally think, feel, and behave in professional settings.
Captures execution and implementation capabilities. Candidates strong in this area excel at driving projects to completion and thrive in structured environments.
These individuals are your reliable performers who ensure deliverables meet deadlines and quality standards.
Reflects influence and change-making abilities. These candidates are energized by creating meaningful transformation and often emerge as natural leaders.
They're essential for roles requiring vision, persuasion, and organizational transformation.
Encompasses relationship-building and team development capabilities. Candidates strong here naturally bring out the best in others and create harmonious work environments.
They're invaluable for collaborative roles, customer service, and team leadership positions.
Captures strategic thinking and visionary capabilities. These individuals excel at seeing patterns, connections, and future possibilities that others miss.
They're crucial for planning, innovation, and analytical roles.
Relates to adaptability and continuous development. Candidates strong in this area demonstrate resilience and openness to change, making them valuable in dynamic environments.
They're particularly valuable during organizational transitions and in rapidly evolving industries.
The comprehensive nature of the Strengths Test allows hiring teams to understand not just what candidates can do, but how they prefer to work and what energizes their best performance. This depth of insight proves invaluable for role matching, team composition, and long-term development planning.
VIA Character Strengths: Assessing Core Values and Motivations
The VIA Character Strengths Survey measures 24 character strengths organized under six core virtues. While less commonly used in hiring than DISC or the Strengths Test, VIA provides unique insights into candidate values and motivations that predict long-term job satisfaction and cultural fit.
Wisdom and Knowledge strengths include creativity, curiosity, judgment, love of learning, and perspective. Candidates strong in these areas thrive in innovative environments, research roles, and positions requiring continuous learning.
Courage encompasses bravery, perseverance, honesty, and zest. These strengths indicate resilience, integrity, and energy—valuable across all roles but particularly important for challenging or high-stakes positions.
Humanity includes love, kindness, and social intelligence. Candidates with these top strengths excel in people-focused roles, team environments, and positions requiring emotional intelligence.
Justice covers teamwork, fairness, and leadership. These strengths predict success in management roles, collaborative environments, and positions requiring ethical decision-making.
Temperance encompasses forgiveness, humility, prudence, and self-regulation. These strengths indicate emotional maturity and self-control, valuable for high-stress roles and leadership positions.
Transcendence includes appreciation of beauty, gratitude, hope, humor, and spirituality. Candidates with these strengths often bring positive energy and perspective to teams, contributing to workplace culture and resilience.
What makes VIA particularly valuable for hiring is its focus on intrinsic motivations and values. While skills can be trained and behaviors modified, character strengths represent deeper motivational patterns that influence long-term job satisfaction and cultural alignment.

Get Started with Our AssessmentsThe Big Five: Foundational Personality Science
While DISC, the Strengths Test, and VIA provide practical hiring insights, the Big Five personality model (OCEAN) offers the strongest scientific foundation for predicting job performance across diverse roles and industries.
Reflects creativity, curiosity, and willingness to try new approaches. High scorers often excel in innovative roles, research positions, and environments requiring adaptability. However, they may struggle in highly structured or routine-based positions where consistency is prioritized over creativity.
Measures reliability, organization, and attention to detail. This trait consistently correlates with job performance across virtually all industries and roles, making it one of the most valuable predictors in hiring. High conscientiousness candidates tend to be punctual, thorough, and goal-oriented.
Indicates energy levels in social situations and preference for collaboration versus independent work. Understanding this helps match candidates to appropriate team structures and client-facing requirements. However, it's important to note that introversion isn't a weakness—many roles benefit from reflective, independent work styles.
Shows cooperation tendencies and conflict resolution styles. While valuable for team harmony and customer service roles, extremely high scores might indicate difficulty making tough decisions or providing critical feedback when necessary.
Reveals stress response patterns and resilience under pressure. This becomes particularly crucial for high-stress roles, leadership positions, or fast-paced environments where emotional regulation directly impacts performance.
Why Smart Companies Use Pre-Employment Personality Tests
After implementing personality assessments across hundreds of hiring processes, we've observed several compelling benefits that extend far beyond basic candidate screening.
Reducing Unconscious Bias
Traditional interviews often favor candidates who remind us of ourselves or who present well in artificial conversation settings. Personality tests provide objective data points that help hiring teams focus on job-relevant traits rather than superficial similarities or differences.
Improving Team Dynamics
Understanding how a potential hire's communication style meshes with existing team members can prevent friction and enhance collaboration. We've seen teams transform their productivity simply by having members who complement each other's working styles.
Predicting Performance Beyond Skills
Technical competence gets someone hired, but personality factors often determine long-term success. A brilliant analyst who can't handle ambiguity may struggle in a startup environment, while a detail-oriented perfectionist might feel overwhelmed in a fast-moving creative agency.
Enhancing Retention Rates
Misaligned personality fit is one of the top reasons employees leave within their first year. By identifying potential mismatches early, companies can make more informed decisions or provide additional support to help new hires succeed.
Supporting Professional Development
Personality insights don't end at hiring. They become valuable tools for managers to understand how to motivate, communicate with, and develop their team members effectively.
Choosing the Right Assessment Model for Your Needs
The effectiveness of personality testing depends heavily on selecting the appropriate assessment framework for your specific hiring challenges and organizational culture.
Use DISC When:
- You need immediate, actionable insights for management and communication
- Team dynamics and collaboration are critical success factors
- You're hiring for sales, customer service, or leadership roles
- Managers need simple frameworks for understanding and motivating different personality types
Use the Strengths Test When:
- You want comprehensive insight across multiple talent dimensions
- Role requirements span various competency areas
- You're building diverse teams requiring complementary strengths
- Long-term development and career planning are organizational priorities
- You need detailed understanding of how candidates naturally approach work
Use VIA Character Strengths When:
- Cultural fit and values alignment are paramount
- You're hiring for mission-driven organizations or roles
- Leadership character and integrity are critical requirements
- Long-term employee engagement and retention are concerns
Use Big Five Assessments When:
- You need scientifically robust data for high-stakes hiring decisions
- Legal defensibility is a primary concern
- You're conducting research on hiring effectiveness
- Cross-cultural hiring requires universal personality frameworks
Many successful organizations combine multiple assessment approaches, using DISC for immediate team fit insights, the Strengths Test for comprehensive talent mapping, and Big Five measures for scientific validation of hiring decisions.
Legal Considerations and Best Practices
This is where many organizations stumble, and it's crucial to get right. Pre-employment personality tests must comply with Equal Employment Opportunity Commission (EEOC) guidelines and demonstrate job relevance to avoid discrimination claims.
Essential Legal Requirements:
- Ensure Job Relevance: Every personality trait you assess must connect directly to job performance requirements
- Avoid Protected Class Discrimination: Tests should not disproportionately impact protected groups
- Use Tests as One Factor: Personality assessments should inform, not make hiring decisions
- Provide Reasonable Accommodations: Plan for candidates with disabilities
- Maintain Confidentiality: Limit access to decision-makers and store results securely
- Choose Validated Instruments: Work with reputable providers who demonstrate compliance
Implementation Framework
The difference between successful and failed personality testing initiatives often comes down to implementation strategy. Here's the framework we recommend:
Start small with one role or department rather than rolling out company-wide. Choose a position where you have clear performance metrics and multiple openings.
Decide which personality framework best serves your needs and where testing fits in your hiring sequence. Many organizations use DISC as an early screening tool, follow with the comprehensive Strengths Test for finalists, and reserve Big Five assessments for senior leadership roles.
Invest heavily in educating hiring managers about interpreting results appropriately. They need to understand what DISC styles mean for day-to-day management, how Strengths Test results inform role design, and how to avoid stereotyping.
Create clear guidelines about how personality test results influence hiring decisions. Document the reasoning behind trait preferences for each role to ensure consistency and legal compliance.
Track metrics like time-to-hire, interview-to-offer ratios, and new hire performance. This data helps you refine the process and demonstrate return on investment.
Measuring Success and ROI
The true value of pre-employment personality testing becomes evident through careful measurement of hiring outcomes:
Future Trends in Personality Testing
As artificial intelligence and data analytics continue evolving, personality testing is becoming more sophisticated:
- AI-Enhanced Interpretation: Advanced algorithms analyze personality data alongside performance metrics for more nuanced insights
- Real-Time Behavioral Assessment: Interactive assessments reveal personality traits through actions rather than self-reports
- Integration with Performance Management: Personality insights inform ongoing development and team assignments
- Predictive Analytics: Organizations build models specific to their culture and role requirements
- Enhanced Candidate Experience: Modern assessments provide value to candidates regardless of hiring outcomes
Making Your Decision
After years of helping organizations implement personality testing programs, we've learned that success depends heavily on realistic expectations and thoughtful execution.
You're a Good Candidate for Personality Testing If:
- Your organization struggles with cultural fit issues or high turnover rates
- You have clearly defined performance expectations and behavioral requirements
- Your hiring team is willing to invest in proper training and implementation
- You're committed to using insights as part of a comprehensive evaluation process
You Should Probably Wait If:
- Your current hiring process lacks basic structure or consistency
- You're looking for a quick fix without addressing underlying issues
- Your organization isn't prepared to invest in proper implementation
- You expect personality tests to eliminate human judgment in hiring
